My invention while capable of a wider use yas a bearing generally, has special use as embodied in the hub' of cycles. such as bicycles, motor-cycles, tricycles, etc.

B The invention has for its general object to simplify the construction of the bearing with a consequent increased economy in the manufacturing, assemblage, and disassemblage of theedevice.

A further important object of the invention is to insure an eective lubrication-of the bearing and the journal such as an axle, shaft, bolt, pin, or other journal element, movably placed in a bearing.

Reference is to be had togthe accompanying drawings forming a part of this specification, it being'understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a side elevation of a bearing embodying my invention with a journal' element in the shape of an axle;

Figure 2 represents a longitudinal vertical section through the bearing, the axle 25 employedV in the resent instance being shown in side elevatlon;

Figure is a longitudinal vertical section of the shell Ior hub of the bearing; v

Figure 4 is a side elevation of the axle;

Figure 5 represents in edge view and' in vertical section one of the elements employed in the bearing and fitting the axle or other joujrna'l element to complete the race for hearing balls;

ing to the bearing for cycles, a shell, hub or box lO'is provided, ixr which the journal here shown as an axle 11, is emplaced. Said journal element 11l has integral collars or annular flanges 12 within the shell 10. Also said shell has adjacent to each enda counterbore 13 presenting an outwardly facing shoulder 113 and a still further en- Figure 6. represents in edge view and in` larged counter'bor 14, Athe shell u counter-bore 14 'being internally threaded.

Bearing elements 15 are fitted on the journal 11 and complete with collars 12 races for bearing balls 16, said bearing elements i5 being accommodated in the counter-bores 3.

Fitting the journal element also outward of the'bearing elements 15 are washers 17 of felt or equivalent material. 'Said felt -washers 17 are received in counter-bores 18 of'oil retaining ring-like elements 19 which are accommodated in the counter-bores 14'of shell 10. Said oil retaining elements 19 are `formed with hubs 20 at the outer ends.

Fitting over the hubs 20 of the oil-retaining elements 19 are rings 21 to hold the oilthe counter-bore 14.

The bearing assemblage is completed 'when the journal element 11 is in place by nuts 24 on the threaded ends of the journal 11, said nuts screwing against the outer faces of the hub 20 of oil-retaining elements 19, said nuts 24. being herel shown asiwing' nuts.

From the foregoing it will be seen that with the shell 10 filled with oil, leakage of the oil will be prevented at the ends of the' bearing by reason of `the elements 15, 17 and 1 19, held in their cooperative relation by the retaining ring 21 and nut 24.

retainingelements 19 in close relation to I would state in conclusion that while the y illustrated example constitutes a practical embodiment of my invention-,I donot limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.

Having thus described my invention, I claim:

In -a bearing, an axle having ,screw threaded ends and provided-with collars a short distance from the screw threaded portions of said ends, a shell having at each end two bores of unequal diameters, the outer and larger bores being internally screw l threaded, apertured and recessed bearing members on the axle in the smaller bore 0f the shell, balls between the said members und the collars 4of the axle, externall7- threaded ring-like members having recesses in their inner faces and provided with hubs on their outer feces, said members screwing in the larger bores of the shell and into engagement with the bearing member, fibrous washers in the recess of the ring-like memment with said members, und nuts on the threaded ends of the axle and adapted Vto screw into engagement with the hub of the ring-like members.

GIUsEPPE sERRAO.
